Design of a Tension Infiltrometer with Automated Data Collection Using a Supervisory Control and Data Acquisition System.

This study highlights the importance of water infiltration in hydrological basin management, emphasizing its role in water services, water quality regulation, and temporal patterns. To measure this crucial function, this study introduces a portable and user-friendly tension infiltrometer designed for easy assembly and data collection. The tension infiltrometer, based on the 2009 design by Spongrová and Kechavarzi, offers a comprehensive characterization of the soil properties related to water flow. It eliminates the influence of preferential flow, providing accurate data. Additionally, it accommodates changes in pore size distribution within the soil, which is crucial for understanding water movement. This study discusses the challenges associated with traditional infiltration measurement tools, like double-ring infiltrometers and single rings, which are not easily transported and can lead to inaccuracies. In response, the proposed infiltrometer simplifies data collection, making it accessible to a broader range of users. This study also explores the use of the VL53L0X distance sensor in the infiltrometer, providing an innovative solution for measuring the water column height. The system's user interface allows real-time data collection and analysis, significantly reducing the processing time compared to that of the manual methods. Overall, this work demonstrates the potential for advancement in hydrological basin management using user-friendly instrumentation and automated data collection, paving the way for improved research and decision making in environmental services, conservation, and restoration efforts within these ecosystems.

Impact of alkaline-earth doping on electronic properties of the photovoltaic perovskite CsSnI3: insights from a DFT perspective.

The oxidation of Sn(II) to the more stable Sn(IV) degrades the photovoltaic perovskite material CsSnI3; however, this problem can be counteracted via alkaline-earth (AE) doping. In this work, the electronic properties of CsSn1-xAExI3, with x = 0 and 0.25, and AE = Mg and Ca, were investigated via Density Functional Theory. It is proven that the synthetic reactions of all these perovskites are thermodynamically viable. Besides, a slight strengthening in the metal-halide bonds is found in the Mg-doped perovskite; consequently, it exhibits the greatest bulk modulus. Nevertheless, the opposite occurrs with the Ca-doped perovskite, which has the smallest bulk modulus due to the weakening of its metal-halide bonds. The calculated bandgaps for CsSnI3, Mg-doped and Ca-doped perovskites are 1.11, 1.32 and 1.55 eV, respectively, remaining remarkably close to the best photovoltaic-performing value for single-junction solar cells of 1.34 eV. Nevertheless, an indirect bandgap was predicted under Mg-doping. These results support the possibility of implementing AE-doped perovskites as absorber materials in single-junction solar cells, which can deliver higher output voltages than that using CsSnI3. Finally, it was found that Sr or Ba doping could result in semiconductors with bandgaps close to 2.0 eV.

HIV Pretreatment Drug Resistance Trends in Mexico City, 2017-2020.

In response to increasing pretreatment drug resistance (PDR), Mexico changed its national antiretroviral treatment (ART) policy, recommending and procuring second-generation integrase strand-transfer inhibitor (INSTI)-based regimens as preferred first-line options since 2019. We present a four-year observational study describing PDR trends across 2017-2020 at the largest HIV diagnosis and primary care center in Mexico City. A total of 6688 baseline protease-reverse transcriptase and 6709 integrase sequences were included. PDR to any drug class was 14.4% (95% CI, 13.6-15.3%). A significant increasing trend for efavirenz/nevirapine PDR was observed (10.3 to 13.6%, p = 0.02). No increase in PDR to second-generation INSTI was observed, remaining under 0.3% across the study period. PDR was strongly associated with prior exposure to ART (aOR: 2.9, 95% CI: 1.9-4.6, p < 0.0001). MSM had higher odds of PDR to efavirenz/nevirapine (aOR: 2.0, 95% CI: 1.0-3.7, p = 0.04), reflecting ongoing transmission of mutations such as K103NS and E138A. ART restarters showed higher representation of cisgender women and injectable drug users, higher age, and lower education level. PDR to dolutegravir/bictegravir remained low in Mexico City, although further surveillance is warranted given the short time of ART optimization. Our study identifies demographic characteristics of groups with higher risk of PDR and lost to follow-up, which may be useful to design differentiated interventions locally.

Resolution of abdominal hernia with loss of home in two surgical times, in a patient with morbid obesity.

Obesity is a risk factor for the development of anterior abdominal wall hernias. Incisional hernias develop in up to 13% of laparotomies: the most difficult to repair are complex and multiple recurrent hernias with significant loss of control. The best approach to treating obese patients who concomitantly have hernias of the anterior abdominal wall is still a matter of debate. We present a clinical case of a patient with morbid obesity and abdominal hernia with loss of residence, who underwent bariatric surgery before ventral plasty.

La obesidad es un factor de riesgo para el desarrollo de hernias de la pared abdominal anterior. Las hernias incisionales se desarrollan hasta en el 13% de las laparotomías. Las más difíciles de reparar son las hernias recurrentes complejas y múltiples con pérdida significativa de domicilio. El mejor enfoque en el tratamiento de pacientes obesos y que concomitantemente tienen hernias de la pared abdominal anterior es aún un tema de debate. Presentamos el caso clínico de un paciente con obesidad mórbida y hernia abdominal con pérdida de domicilio, intervenido de cirugía bariatrica antes de la plastia ventral.

Characteristics and growth of the genetic HIV transmission network of Mexico City during 2020.

INTRODUCTION: Molecular surveillance systems could provide public health benefits to focus strategies to improve the HIV care continuum. Here, we infer the HIV genetic network of Mexico City in 2020, and identify actively growing clusters that could represent relevant targets for intervention. METHODS: All new diagnoses, referrals from other institutions, as well as persons returning to care, enrolling at the largest HIV clinic in Mexico City were invited to participate in the study. The network was inferred from HIV pol sequences, using pairwise genetic distance methods, with a locally hosted, secure version of the HIV-TRACE tool: Seguro HIV-TRACE. Socio-demographic, clinical and behavioural metadata were overlaid across the network to design focused prevention interventions. RESULTS: A total of 3168 HIV sequences from unique individuals were included. One thousand and one-hundred and fifty (36%) sequences formed 1361 links within 386 transmission clusters in the network. Cluster size varied from 2 to 14 (63% were dyads). After adjustment for covariates, lower age (adjusted odds ratio [aOR]: 0.37, p<0.001; >34 vs. <24 years), being a man who has sex with men (MSM) (aOR: 2.47, p = 0.004; MSM vs. cisgender women), having higher viral load (aOR: 1.28, p<0.001) and higher CD4+ T cell count (aOR: 1.80, p<0.001; ≥500 vs. <200 cells/mm3 ) remained associated with higher odds of clustering. Compared to MSM, cisgender women and heterosexual men had significantly lower education (none or any elementary: 59.1% and 54.2% vs. 16.6%, p<0.001) and socio-economic status (low income: 36.4% and 29.0% vs. 18.6%, p = 0.03) than MSM. We identified 10 (2.6%) clusters with constant growth, for prioritized intervention, that included intersecting sexual risk groups, highly connected nodes and bridge nodes between possible sub-clusters with high growth potential. CONCLUSIONS: HIV transmission in Mexico City is strongly driven by young MSM with higher education level and recent infection. Nevertheless, leveraging network inference, we identified actively growing clusters that could be prioritized for focused intervention with demographic and risk characteristics that do not necessarily reflect the ones observed in the overall clustering population. Further studies evaluating different models to predict growing clusters are warranted. Focused interventions will have to consider structural and risk disparities between the MSM and the heterosexual populations.

Genome-Wide Association Study Identifies a Functional SIDT2 Variant Associated With HDL-C (High-Density Lipoprotein Cholesterol) Levels and Premature Coronary Artery Disease.

Objective: Low HDL-C (high-density lipoprotein cholesterol) is the most frequent dyslipidemia in Mexicans, but few studies have examined the underlying genetic basis. Our purpose was to identify genetic variants associated with HDL-C levels and cardiovascular risk in the Mexican population. Approach and Results: A genome-wide association studies for HDL-C levels in 2335 Mexicans, identified four loci associated with genome-wide significance: CETP, ABCA1, LIPC, and SIDT2. The SIDT2 missense Val636Ile variant was associated with HDL-C levels and was replicated in 3 independent cohorts (P=5.9×10−18 in the conjoint analysis). The SIDT2/Val636Ile variant is more frequent in Native American and derived populations than in other ethnic groups. This variant was also associated with increased ApoA1 and glycerophospholipid serum levels, decreased LDL-C (low-density lipoprotein cholesterol) and ApoB levels, and a lower risk of premature CAD. Because SIDT2 was previously identified as a protein involved in sterol transport, we tested whether the SIDT2/Ile636 protein affected this function using an in vitro site-directed mutagenesis approach. The SIDT2/Ile636 protein showed increased uptake of the cholesterol analog dehydroergosterol, suggesting this variant affects function. Finally, liver transcriptome data from humans and the Hybrid Mouse Diversity Panel are consistent with the involvement of SIDT2 in lipid and lipoprotein metabolism. Conclusions: This is the first genome-wide association study for HDL-C levels seeking associations with coronary artery disease in the Mexican population. Our findings provide new insight into the genetic architecture of HDL-C and highlight SIDT2 as a new player in cholesterol and lipoprotein metabolism in humans.

Un nuevo método no invasivo en la valoración integral de la fibrilación auricular por tomografía cardíaca / A novel, non-invasive, integral imaging assessment in atrial fibrillation by cardiac tomography

Resumen Objetivo: Analizar la utilidad clínica y la viabilidad de la tomografía cardíaca multidetector (TCMD) en la valoración de pacientes con fibrilación auricular (FA). Material y métodos: Estudio prospectivo de casos y controles en 84 sujetos (54 con FA y 30 controles). La morfología de la orejuela izquierda (OI) se clasificó en cactus, ala de pollo, manga de viento y coliflor. La presencia de trombo en la OI, el antecedente de accidente cerebrovascular y la escala CHA2DS2-VASc se compararon con parámetros obtenidos por TCMD. Resultados: La fracción de expulsión de la aurícula izquierda (FEAI) y la fracción de expulsión de la orejuela izquierda (FEOI) fueron más bajas en los individuos con FA (p < 0.001). El volumen indexado de la aurícula izquierda (VIAI) fue mayor en los pacientes con FA (p < 0.001). Se observó una correlación inversa entre la FEAI y el VIAI (r = -0.38, p < 0.001). La morfología tipo coliflor fue la más frecuente en enfermos con FA, mientras que la de tipo cactus predominó en los controles. La de tipo coliflor fue la más relacionada con presencia de trombos (p < 0.01), así como una calificación CHA2DS2-VASc alta. La velocidad de flujo fue menor en los pacientes con FA (p < 0.001). Conclusión: La TCMD es un método novedoso y no invasivo para una valoración integral en la FA. Los resultados de este estudio podrían mejorar la precisión, la utilidad clínica y el análisis de estratificación del riesgo en la FA. Los autores proponen incluir este nuevo método en la valoración integral del riesgo tromboembólico en pacientes con FA.

Abstract Objective: To analyze the clinical utility and feasibility of the multidetector cardiac tomography (MDCT) in multi-parametric imaging assessment in atrial fibrillation (AF) patients. Material and methods: Prospective case-control study in 84 subjects (54 AF subjects and 30 healthy subjects). Left atrial appendage (LAA) morphology was classified as: cactus, chicken wing, wind sock, cauliflower. Intra-cardiac thrombus, stroke history and CHA2DS2-VASC scale were compared to cardiac MDCT atrial imaging assessment. Results: Left atrial ejection fraction (LAEF) and LAA ejection fraction (LAAEF) were lower in AF subjects (p < 0.001), left atrial volume index (LAVI) was higher in AF subjects (p < 0.001). An inverse correlation between LAEF and LAVI was found (r = −0.38, p < 0.001). Cauliflower LAA morphology frequency was higher in AF subjects, whereas cactus LAA morphology frequency was higher in controls. Cauliflower LAA morphology was associated with thrombus presence (p < 0.01) as well as a higher CHA2DS2-VASc score. Flow velocity were lower in AF subject compared to controls (p < 0.001). Conclusion: MDCT is a novel, non-invasive, worldwide available method for an integral assessment in AF. Our results could improve precision, clinical utility and risk stratification analysis in AF. Our proposal is to include this new method into the global cardiovascular and thrombotic risk assessment in AF patients.

Psychological impact of COVID-19 pandemic among healthcare workers in Paraguay: A descriptive and preliminary study

ABSTRACT Introduction: Healthcare workers exposed to SARS-CoV-2 are vulnerable to psychological distress. Methodology: A descriptive cross-sectional study was carried out in 5 tertiary hospitals in the Central, San Pedro and Caaguazú Departments of Paraguay during the COVID-19 pandemic from April to June 2020. The pilot study included 125 healthcare workers as participants, 25 for each hospital. Demographic data and occupational exposure data were collected with an ad-hoc questionnaire. Symptoms of depression and anxiety were evaluated employing the Patient Health Questionnaire-9, and the Generalized Anxiety Disorder scale-7. The prevalence of post-traumatic stress was determined using the Post-Traumatic Stress Disorder Check List-C. Results: Of the 125 participants, 68 (54.8%) were doctors, 37 (29.8) nurses, 7 (5.6%) biochemists, 3 (2.4%) obstetricians, and 9 (7.3%) other healthcare workers. Most participants were females (86 (68.8%)), with an average age of 33.8 years (SD ± 7.4), single (71 (56.8%)), with a postgraduate educational level (83 (66.4%)), and reporting a junior level of work experience (52 (41.6%)). A total of 71 (57.3%) were classified as high-risk healthcare workers after exposure to SARS-CoV-2. 61 (48.8%) of participants presented symptoms of depression, and 68 (54.4%) presented symptoms of anxiety. A small group reported symptoms of post-traumatic stress (9 (7.2%)). Conclusion: Healthcare workers in Paraguay reported a significant prevalence of depressive and anxious symptoms during the COVID-19 pandemic. These findings lend support to the idea that healthcare workers are vulnerable to psychological distress and that they may require specific mental health interventions.

Un total de 71 (57,3%) fueron clasificados como trabajadores de la salud de alto riesgo después de la exposición al SARS-CoV-2. 61 (48,8%) de los participantes presentaron síntomas de depresión y 68 (54,4%) presentaron síntomas de ansiedad. Conclusión: los trabajadores de la salud en Paraguay reportaron una prevalencia significativa de síntomas depresivos y ansiosos durante la pandemia de COVID-19. Estos hallazgos apoyan la idea de que los trabajadores de la salud son vulnerables a la angustia psicológica y que pueden requerir intervenciones específicas de salud mental.

Self-Perceived Stress During the Quarantine of COVID-19 Pandemic in Paraguay: An Exploratory Survey.

Introduction: Any viral pandemic is a global health and mental health issue. The World Health Organization and mental health associations have warned that the current COVID-19 pandemic will lead to a drastic increase of stress-related conditions and mental health issues globally. Materials and Methods: An online web-based survey has been launched from 10 to 15 April 2020 in Paraguay in order to collect information regarding the stress related to the quarantine during the COVID-19 pandemic. It has been spread through social media ("WhatsApp," "Twitter," and "Facebook"). Two thousand two hundred and six Paraguayan citizens, over 18 years of age, completed the survey voluntarily. Socio-demographics as well as ratings at Self-perceived Stress Scale have been collected and analyzed. Results: Two thousand two hundred and six subjects (74.12% men) aged between 18 and 75 with an average of 34 ± 11 years old completed the survey. 12.42% (276 subjects) of sample reported a preexisting diagnosis of mental disorder, and 175 participants (7.93%) reported an increase of preexisting symptoms with the onset of COVID-19 quarantine. 41.97% of them had anxiety and 54.38% did not receive any specific treatment. The general population rated 18.10 ± 5.99 at Self-perceived Stress Scale, which indicates a moderate level of self-perceived stress. Significant association was found between higher levels of stress and female sex, being single, or reporting preexisting mental disorder, above all anxiety and depression (p < 0.01). In fact, in 63.87% of mentally ill subjects (n = 175), the quarantine has worsened symptoms of preexisting mental disorders. Conclusion: This study suggests a stressful impact of COVID-19 pandemic, with the majority of participants reporting a moderate level of self-perceived stress. We suggest mental health services to provide a phone-based or web-based support to the general population in order to contrast the psychological impact of the pandemic. This approach may improve the accessibility to mental healthcare services in Paraguay, especially in times of social distancing.

La morfología tipo coliflor fue la más frecuente en enfermos con FA, mientras que la de tipo cactus predominó en los controles. La de tipo coliflor fue la más relacionada con presencia de trombos (p < 0.01), así como una calificación CHA2DS2-VASc alta. La velocidad de flujo fue menor en los pacientes con FA (p < 0.001). Conclusión: La TCMD es un método novedoso y no invasivo para una valoración integral en la FA. Los resultados de este estudio podrían mejorar la precisión, la utilidad clínica y el análisis de estratificación del riesgo en la FA. Los autores proponen incluir este nuevo método en la valoración integral del riesgo tromboembólico en pacientes con FA.

Effects of lithium on the electronic properties of porous Ge as anode material for batteries.

Recently, the need of improvement of energy storage has led to the development of Lithium batteries with porous materials as electrodes. Porous Germanium (pGe) has shown promise for the development of new generation Li-ion batteries due to its excellent electronic, and chemical properties, however, the effect of lithium in its properties has not been studied extensively. In this contribution, the effect of surface and interstitial Li on the electronic properties of pGe was studied using a first-principles density functional theory scheme. The porous structures were modeled by removing columns of atoms in the [001] direction and the surface dangling bonds were passivated with H atoms, and then replaced with Li atoms. Also, the effect of a single interstitial Li in the Ge was analyzed. The transition state and the diffusion barrier of the Li in the Ge structure were studied using a quadratic synchronous transit scheme.

Psicodermatología: una introducción a sus conceptos, nosología y modelos de abordaje / Psychodermatology: An introduction to its concepts, nosology and approach models

Es imposible separar la enfermedad física de la enfermedad mental, puesto que la fisiopatología de cualquier enfermedad contiene a la esfera psicológica dentro de sus múltiples elementos. En ese sentido, muchas especialidades médicas pueden reclamar su relación con la Psiquiatría, puesto que son innumerables las enfermedades que tienen nexo con signos y síntomas psiquiátricos (por ejemplo, la enfermedad inflamatoria intestinal en Gastroenterología; el asma bronquial en Neumología, entre otras). No obstante, con la Dermatología la relación es mucho más evidente. La Psicodermatología es una especialidad que surge de la conjunción de dos ramas aparentemente divergentes de la Medicina: la Psiquiatría y la Dermatología. En Psicodermatología, algunos pacientes presentan enfermedades principalmente dermatológicas con comorbilidades psicosociales secundarias, mientras que otros tienen trastornos psiquiátricos primarios con sintomatología cutánea significativa. Así también, debido a que varias enfermedades dermatológicas no solo se acompañan frecuentemente de dolor e incomodidad, sino que son inmediatamente visibles para los demás, las personas afectadas por estas condiciones pueden sufrir consecuencias sociales y emocionales. Con base en lo anterior, este artículo de revisión presenta los conceptos, nosología y modelos de abordaje de esta ciencia médica, haciendo hincapié que, debido a la interacción permanente entre la mente y la piel, se hace necesario que el paciente sea tratado como una unidad constituida por varios niveles, incluyendo aspectos cutáneos, emocionales y mentales.

It is impossible to separate the physical illness from the mental illness, since the pathophysiology of any disease contains the psychological sphere within its multiple elements. In this sense, many medical specialties can claim their relationship with Psychiatry, since there are innumerable diseases that have a link with psychiatric signs and symptoms (for example, inflammatory bowel disease in Gastroenterology; bronchial asthma in Pneumology, among others). However, with Dermatology the relationship is much more evident. Psychodermatology is a specialty that arises from the conjunction of two apparently divergent branches of Medicine: Psychiatry and Dermatology. In Psychodermatology, some patients present mainly dermatological diseases with secondary psychosocial comorbidities, while others have primary psychiatric disorders with significant cutaneous symptoms. Also, because various dermatologic diseases are not only frequently accompanied by pain and discomfort, but are immediately visible to others, people affected from these conditions can suffer social and emotional consequences. Based on the above, this review article presents the concepts, nosology, and approach models of this medical science, emphasizing that due to the permanent interaction between the mind and the skin, it is necessary for the patient to be treated as an unit made up of several levels, including cutaneous, emotional and mental aspects.

Biocomposites from Rice Straw Nanofibers: Morphology, Thermal and Mechanical Properties.

Agricultural residues are major potential resources for biomass and for material production. In this work, rice straw residues were used to isolate cellulose nanofibers of different degree of oxidation. Firstly, bleached rice fibers were produced from the rice straw residues following chemical extraction and bleaching processes. Oxidation of rice fibers mediated by radical 2,2,6,6-tetramethylpiperidine 1-oxyl (TEMPO) at pH 10 was then applied to extract rice cellulose nanofibers, with diameters of 3-11 nm from morphological analysis. The strengthening capacity of rice nanofibers was tested by casting nanocomposite films with poly(vinyl alcohol) polymer. The same formulations with eucalyptus nanofibers were produced as comparison. Their thermal and mechanical performance was evaluated using thermogravimetry, differential scanning calorimetry, dynamic mechanical analysis and tensile testing. The glass transition of nanocomposites was shifted to higher temperatures with respect to the pure polymer by the addition of rice cellulose nanofibers. Rice nanofibers also acted as a nucleating agent for the polymer matrix. More flexible eucalyptus nanofibers did not show these two phenomena on the matrix. Instead, both types of nanofibers gave similar stiffening (as Young's modulus) to the matrix reinforced up to 5 wt.%. The ultimate tensile strength of nanocomposite films revealed significant enhancing capacity for rice nanofibers, although this effect was somehow higher for eucalyptus nanofibers.

Psychopharmacology in dermatology: Treatment of primary psychiatric conditions in dermatology.

The role of psychotropic drugs in psychodermatology is still debatable, due to the quality of the evidence that supports it. There are several case reports and open trials with variable results. There is an additional difficulty in finding therapists trained in effective psychotherapy techniques, justify the need for more research on the available pharmacological options. The present review emphasizes pharmacological treatment in psychodermatology, specifically in cases of primary psychiatric disorders that are expressed with self-inflicted cutaneous signs and symptoms, in which drugs can play a central role in ameliorating symptoms or be useful in combination with psychotherapeutic approach of these disorders.
